Engineer's Note

Compared with the previous-generation MZWLL1T6HAJQ-00005, the Samsung PM1735 MZWLR1T6HBJR-00AD3 upgrades to PCIe Gen4 x4 and delivers up to 7,000 MB/s sequential read and 1,000,000 random-read IOPS, giving server platforms a clear generational lift in bandwidth and transactional responsiveness. Its 1.6 TB Samsung V-NAND 3D TLC design, backed by 3 DWPD and 8,760 TBW, makes it a strong fit for write-intensive virtualization, OLTP databases, and caching tiers that need higher endurance without sacrificing top-tier read performance.

Endurance & Reliability

With an endurance rating of 8,760 TBW and 3 DWPD, this SSD is designed to handle very heavy write activity over its service life, making it far more than sufficient for typical OS, application, boot, logging, and general server workloads. In practical terms, for a system-drive or read-heavy enterprise deployment, this level of endurance supports long-term use with a wide operating margin and gives buyers strong confidence in sustained reliability. Its built-in Power Loss Protection (PLP) helps preserve in-flight data and critical mapping information during an unexpected power outage, reducing the risk of corruption and improving operational safety. An UBER of 1.0E-17 means the drive is engineered for extremely low unrecoverable read error rates, which is a key enterprise-class characteristic for protecting data integrity in continuous-use environments.

Technical Specs & Insights

1. The PCIe Gen4 x4 host interface unlocks full modern server bandwidth, helping storage-intensive platforms eliminate I/O bottlenecks during large dataset ingestion and VM boot storms.
2. Its class-leading sequential read performance accelerates full-drive scans, backup restores, and analytics jobs that stream massive files from storage.
3. The million-class random read capability keeps database indexes, metadata lookups, and virtualized workloads highly responsive even under heavy parallel access.
4. With a 3 DWPD endurance rating, this drive is built for write-intensive enterprise deployments such as caching, logging, and mixed-use transactional systems with sustained daily rewrites.
5. Samsung V-NAND 3D TLC combined with sub-100-microsecond typical latency delivers a strong balance of density, efficiency, and consistently fast response times for latency-sensitive cloud and enterprise applications.

Capacity Sweet

Lower capacity reference: 800 GB Higher capacity reference: 3.2 TB In this enterprise SSD family, 1.6 TB sits at the practical sweet spot. Compared with the 800 GB model, it offers noticeably more headroom for OS images, application growth, logs, and overprovisioning, reducing the need for early capacity expansion. Compared with the 3.2 TB version, it keeps acquisition cost and fleet standardization more manageable while delivering broadly similar sequential throughput and random IOPS for mainstream enterprise workloads. This makes 1.6 TB especially well suited for mid-scale virtualization clusters, such as shared storage pools supporting about 40 to 60 general-purpose virtual machines.
